7. If the USPS is so unnecessary, why are BOTH FedEX and UPS using them

As part of their package delivery strategies?

In many rural locations, neither of the commercial delivery services want to provide service, and the USPS does it so efficiently and so cheaply that it is more profitable for them to pay USPS to do the final deliveries. If the USPS folds, expect delivery of packages and information to cost many times what it does now.

Here, we get bills, magazines, packages, books, advertising, and mailings from the US government.

The USPS would be profitable if they had not been burdened with pre-funding retirement, far more than any other company or government entity has ever been required to do. That they are still close to being viable even with that burden, is a tribute to how efficient the USPS is.
